A cough is one of the most common medical complaints accounting for as many as 30 million clinical visits per year. The term closing capacity refers to the volume of gas present in the lungs when the small airways begin to collapse.76 In infants, closing capacity exceeds FRC. Lung volume and cardiorespiratory changes during open and closed endotracheal suction in ventilated newborn infants, Volume not guaranteed: closed endotracheal suction compromises ventilation in volume-targeted mode, The effect of suction method, catheter size, and suction pressure on lung volume changes during endotracheal suction in piglets, Closed suctioning of intubated neonates maintains better physiologic stability: a randomized trial, Effect of closed endotracheal suction in high-frequency ventilated premature infants measured with electrical impedance tomography, Physiologic impact of closed-system endotracheal suctioning in spontaneously breathing patients receiving mechanical ventilation, Effect of endotracheal suction on lung dynamics in mechanically-ventilated paediatric patients, Saline instillation before tracheal suctioning decreases the incidence of ventilator-associated pneumonia, A low-sodium solution for airway care: results of a multicenter trial, Endotracheal suctioning: there's more to it than just technical care, Ventilator-associated pneumonia or endotracheal tube-associated pneumonia? We should widely embrace therapies that support the patient's natural airway-clearance mechanisms.

Airway-clearance techniques may be of benefit in minimizing re-intubation in neonates, but are of little or no benefit in the treatment of acute asthma, bronchiolitis, or neonatal respiratory distress, or in patients mechanically ventilated for acute respiratory failure, and it is not effective in preventing postoperative atelectasis. Bicarbonate, mucolytics, and those types of things: are they actually helpful? Eliminating expensive and unproven therapies could help with the financial case for the additional resources needed for a respiratory-based program. Clearly, suctioning without a cough will only clear the ETT. Physical activity and exercise programs have been shown to augment airway clearance. Not surprisingly, open suctioning produced a greater lung-volume loss.56 Note, however, that 4 of the 10 HFOV patients were receiving muscle relaxants, and those paralyzed patients had the longest recovery times.53 This could correlate to the fact that paralyzed patients are often sicker. Intrapulmonary percussive ventilation is intriguing; I think it does that by using fairly large volumes. Department of Respiratory Care, Children's Medical Center Dallas, Dallas, Texas. The oldies but goodies. It mostly develops from acute lung injury. Clinicians need to be willing to weigh the pros and cons of therapies that may hinder this natural defense. Caruso's 2009 study of 262 adult patients found a VAP risk reduction of 54% with routine saline instillation.61 A limitation of that study may be that HMEs were utilized to provide humidification, possibly necessitating saline instillation for secretion thinning. Outside of the neonatal ICU, with large-VT recruitment, it just depends on how much of an advocate you are and how much volutrauma it creates. The negative pressure from the suction catheter triggers the ventilator, and the incoming gas forces the secretions away from the suction catheter. It seems to be kind of a bell-curve effect, where the 6.5 to 7.0 range promotes bacteria growth. Have you had any experience with that? 1). The mucus is then propelled out of the airway. I'm interested in seeing some controlled studies, rather than just approval, but it does potentially make sense to use that as opposed to something like saline. An important clinical advantage to heated-wire circuits is the reduction in circuit condensate. The ventilation mode markedly affects VT during closed suctioning. Bicarbonate is incredibly irritating, has minimal effect on the airway secretion rheology, and may cause patients to cough, which could potentially be considered a benefit. If not, what are your personal views? Yet these are missing in infants in which these collaterals are not well developed. The management of patients during their non-acute phase offers a guide. Maternal Newborn Ch. 29 NCLEX Q's Flashcards | Quizlet This loss of volume may shift fissures toward the area of atelectasis, or cause mediastinal shift toward the affected side. 8.3 Applying the Nursing Process - Nursing Fundamentals The most common risk for nursing diagnoses in the first assessment were risk for infection (00004), risk for injury (00035), risk for delayed development . I think that does sometimes drive practice inappropriately. Following the introduction of heated high-flow nasal cannula, all the respiratory syncytial virus infants received humidified gas, some with only humidified air. CPT and intrapulmonary percussive ventilation are given a time standard of 20 min, and high-frequency chest compression and PEP therapy are determined to be 15 min. Catheter insertion alone may dislodge thousands of bacteria; a flush of saline increases this and potentially distributes them distally into the lung, fostering the concern that routine saline instillation may increase the incidence of VAP. There are studies of the multiple variations of this technique.2,3 Postural drainage can be performed with or without percussion or vibration. Neonates struggle to maintain FRC and most often breathe well below closing capacity. Endotracheal suctioning is basic intensive care or is it? Problem: Risk for Ineffective Airway clearance r/t the excessive fluid and mucus in the newborn's respiratory passages. The smarter suctioning approach consists of suctioning only when a clinical indication arises, not on a scheduled basis.51 In the neonatal population, limitation of pre-oxygenation to 1020% above baseline FIO2 is often recommended.51 When developing standards for tracheal suctioning, healthcare providers should address catheter size, duration of suctioning, suctioning pressure, deep versus shallow technique, open versus closed technique, saline instillation, lung pathology, and ventilation mode. Some support the cough and respiratory effort or drive by utilizing noninvasive ventilation to limit fatigue, whereas others utilize PEP therapy to prevent distal airway collapse. These include: acid reflux seizures coma cancer in any part of the upper digestive system, such as the mouth, throat, and esophagus head and neck injuries stroke eating and drinking too fast dental issues mouth sores A recent study in neonates compared routine use of a low-sodium solution versus routine use of normal saline. Ineffective Airway Clearance May be related to Copious secretions Decreased energy and fatigue Presence of artificial airway: tracheostomy Thick secretions Possibly evidenced by Abnormal breath sounds (crackles, rhonchi) Dyspnea Ineffective cough Increased breathing effort: nasal flaring, intercostal retractions, use of accessory muscles Saline instillation prior to suctioning remains a controversial topic in pediatrics, particularly with neonates. The chest wall is also more difficult to stabilize under gravitational pressure. A plateau pressure of 40 cm H2O for 40 seconds is just not long enough to recruit the whole lung. Some models of mechanical percussor or vibrator are appropriate only for the newborn or premature infant, whereas other models provide a stronger vibration appropriate for the larger child. I would like the therapist to focus more on the physiology of why you're having to use a higher FIO2 to get the SpO2 up, and to not to leave the bedside if the patient's not back down to their baseline FIO2. Obstructed airways could impair ventilation/perfusion matching. The clinical picture of airway collapse often prompts CPT or bronchodilator orders. Frequent positioning helps prevent the pooling of secretions in the lungs and prevents alveoli from collapsing. We've been able to manipulate pH to some extent, having shown that alters either the rheology or the transportability of secretions. Just a bunch of fairly randomly directed comments. Is there equipoise? As our profession matures, we hope that practices like this will not evolve without substantial research to ensure that we are not contributing to the high cost of healthcare or, even more importantly, are not causing harm. Wherever possible we have chosen pediatric-specific evidence to support our conclusions. However, if during a tussive squeeze the positive pleural pressure exceeds that of the airway pressure, the airway may collapse. Keep the head of the bed elevated at least 30 degrees at all times. NANDA Nursing Diagnoses List 2023.pdf - Course Hero The effectiveness of airway maintenance and clearance depends a great deal on the biochemical and biophysical characteristics of mucus. Nursing diagnoses of preterm infants in the neonatal intensive care CF is the best disease to review because CF involves mucociliary transport dysfunction. Since respiratory disease is the most common diagnosis among acute pediatric patients admitted to the hospital,75 unnecessary airway-clearance therapies substantially increase costs to the patient and hospital. Patients with secretions to aspirate may not experience that degree of resistance or compliance change, but potential risk exists. While the patient is in the various postural drainage positions, the clinician percusses the chest wall with a cupped hand, pneumatic or electro-mechanical percussor, or a round sealed applicator. A select few will retest theories of yesterday, such as routine CPT, negative-pressure ventilation, and suctioning with or without saline. Thank you for including the study on suctioning and VAP prevention,1 which was interesting to me because I see the wholesale banning of suctioning in the neonatal ICU because of concern about VAP prevention. I wouldn't recommend it as a way of clearing secretions. Thick and viscid mucus is such a common feature that at one time the disease was referred to as mucoviscidosis.84, Mucociliary clearance is variable in CF, with some patients having severe impairment, whereas others have normal clearance. This builds a large back-pressure rather quickly. Sometimes it takes 510 cm H2O above on the ventilator to achieve that, but I try to stay below a peak pressure of 35 cm H2O during re-recruitment maneuvers. d. Altered Nutrition: More than Body Requirements., What would be important abnormal information to note upon the initial physical . Diagnoses. We generalize what is known and written about bronchial hygiene in adults, but the important differences in children cannot be ignored. The question arises as to what is appropriate airway clearance in an acute disease process? Research supports the use of closed-system suctioning. So instillation of saline and the immediate aspiration of saline does make some senseinstillation of saline and then deep bagging it into the lung and then putting in a suction catheter down into the tube makes no sense whatsoever. Risk for infection related to lowered immune response in newborn. In one institution we didn't do it at all: it was physical therapy and nursing, because the director didn't advocate for it because of a lack of evidence. In the CF patient there is an increased number of goblet cells and hypertrophy of submucosal glands, which leads to an increase in secretions and sputum production. This action results in swollen turbinates, which can lead to nasal congestion and increase airway resistance, thus escalating a patient's respiratory work load.44. To prevent volume loss, one should limit the overall suctioning procedure time, not just the actual suctioning time.
